What is a MDU?
The MDU-G4 mechanical drive unit is a high-performance steering actuator designed to provide high precision steering when coupled to a GPS automated steering system. The MDU-G4 was designed for ease of installation, portability between vehicles and a long service life. The MDU-G4 uses a reliable high torque DC motor and a robust and simple gear drive for fast and responsive steering under all field steering conditions. The unique split gear design and quick-release latch makes for an easy installation that does not require the removal of the steering wheel so you gain time and are also able to easily transfer your MDU-G4 between many.
